LGU1J122MELZ

The LGU1J122MELZ is a Nichicon aluminum electrolytic capacitor in a snap-in terminal, radial can package. It provides 1.2 mF (1200 µF) capacitance at a 63 V rated voltage with polarized construction for general-purpose power applications.

Designed for production use, this part combines high ripple capability, extended high-temperature endurance and a compact φ22 × 25 mm can for reliable bulk energy storage and filtering in industrial and electronic equipment operating between −40°C and 105°C.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a 63 V rated voltage; capacitance tolerance ±20% at 120 Hz, 20°C.
• High Ripple Current — Rated ripple current of 1.25 A at 120 Hz and 1.438 A at 50 kHz, supporting applications with significant AC ripple on DC rails.
• Low Leakage — Leakage current specified at 820 µA, measured after standard voltage application at 20°C.
• Extended Endurance — Withstands rated ripple current at 105°C for 3000 hours per the LGU series endurance specification.
• Wide Temperature Range — Operates from −40°C to 105°C to suit a broad range of ambient conditions.
• Snap-in, Radial Can Package — φ22 × 25 mm (L: 2.5 × D: 2.2 cm) snap-in can for robust PCB mounting; supplied in tray packing for mass production.
• RoHS Compliant — Meets RoHS environmental requirements for lead-free manufacturing.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling on low-voltage DC rails where 63 V rating and high capacitance are required.
• Power supply energy storage — Local energy reservoir for regulated supplies and power modules that experience ripple currents up to specified ratings.
• Industrial and electronic equipment — Applications requiring durable electrolytic capacitance across −40°C to 105°C operating range and long endurance at elevated temperature.

Unique Advantages

• Designed for sustained ripple loading — Specified ripple current ratings (1.25 A at 120 Hz; 1.438 A at 50 kHz) help maintain capacitor performance under AC stress.
• Long high-temperature life — 3000 hours endurance at 105°C with rated ripple current applied provides predictable aging characteristics for production designs.
• Compact, production-ready packaging — Snap-in radial can (φ22 × 25 mm) with tray packing supports automated board assembly and volume manufacturing.
• Controlled leakage — Low leakage current (820 µA) supports reliable DC performance after voltage application.
• Broad operating temperature range — −40°C to 105°C suitability expands use across varied environmental conditions.
• RoHS compliance — Enables integration into lead-free, environmentally conscious product lines.
